To all whom it may concern: Y

Be it known that I, Hoi/inn E. Swnn'r, a citizen of the United States,residing at Portland, in the county of Multnomah and State of Oregon,have invented certain new and useful Improvements in Cutlery- Grinders;and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appcrtains to make and use the/same.

This invention relates to improvements in cutlery grinders and moreparticularly to the means for holding the cutlery in proper position forgrinding.

One object of the invention is to provide an improved construction ofcutlery holding mechanism having means whereby a knife, scissor blade orother form of cutlery may be held in position against the grindstone.

Another object is to provide a holder of this character which may beadjustably secured to any suitable support.

lVith the foregoing and other objects in view, the invention consists ofcertain novel features of construction, combination and arrangement ofparts, as will be more fully described and particularly pointed out inthe appended claims.

In the accompanying drawings, Figure l is a side View, partly in sectionof my improved holder anda portion ofa grindstone, showing one way inwhich a knife blade is supported for grinding; Fig. 2 is a similar Viewshowing another way in which the blade may be supported; Fig. 3 is asimilar view, showing a scissor blade held in position for grinding;Fig. 4 is a front elevation of the holder and grindstone.

Referring more particularly to the drawlings, l denotes a grindstonewhich may be i of any suitable construction and which may be supportedand operated in any suitable manner. y My improved supporting mechanismcomprises a standard 2 having a right angularly formed longitudinallyslotted base 3 in which is arranged a clamping screw 4 whereby the baseand standard may be adjust-ably secured to any suitable support.

2 are formed angular inwardly inclined tool or cutlery sup ortingsurfaces or rests 5 and 6 which are disposed at dierent inclinations andon the inner edge or side of the standard adjacent to its lower ends isformed a tool supporting seat 7. The sup- On the upper end of thestandard porting surface or rest 5 and the seat 7 are provided tosupport and hold a knife blade in position for grinding the edge of thesame by the adjacent side of the grindstone. The

manner in which the blade is engaged with the seat 7 and held againstthe grindstone is clearly shown in Fig. l of the drawings.

vIn Fig. 2 of the drawing, is shown the manner in which the blade isheld by the supporting surface or rest 5 when engaged by the grindstone.`When the rest :3 is employed, the holder is preferably adjusted tobring the lower end of said surface into engagement with the hollowcentral portion of the stone and when in this position, the angle' ofthe surface or resty 5 serves as a gage and holds the edge of the bladeagainst the stone.

lVhen the holder is employed for supporting a scissor blade, said holderis adjusted to the position shown in Fig. 3 of the drawings and theblade is engaged with the supporting surface or rest. 6 so that the edgeofthe blade will engage the side of the stone at the proper angle. Whenusing the device for holding a scissor blade, l preferably employ ablade clamping spring 8, one end of which is secured to the underside ofthe rest G, while the other end is adapted to bear against the scissorblade and to clamp the same into engagement with the rest G, as shown.In addition to the clamping spring 8, l also preferably'employ a spring9 for moving and holding the blade against the grindstone, as clearlyshown in Fig. 3 of the drawings. The spring 9 is formed from a singlepiece of wire bent into approximately lJ-shaped form. The terminals ofthe wire are attached to the outer face of the standard and are bent toform coils 10, while the side pieces of the spring straddle the upperend of the standard and the spring 8 and are adapted to engage and holda tool against t-he grind stone.

By means of a holding device constructed as herein shown and described,a. knife or scissor blade may be securely held in roper position forengagement with a grin stone, whereby a keen, even edge will be formedon the blade.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwillbe readily understood without requiring a more extended explanation.Various changes in the form, proportion and the minor detailsofconstruction may be resorted to Without departing from the principleor sacrificing any of the advantages of the invention, as defined inthe'appended claims.

Having thus described my invention, what I claim is: i

l. A tool holder of the class described comprising a supporting standardhaving portions of its outer end formed to provide a pair of inwardlyinclined cutlery supporting surfaces which are disposed at di erentinclinations and are adapted to support different forms of tool bladesin position for grinding, a longitudinally slotted base for vthestandard and a clamping screw passingthrough the slot of the base forholding the standard in adjusted position. Y

2. A tool holder ofA the class described comprising 'a supportingstandard having portions of its outer end formed to provide a pair ofinwardly inclined cutlery su porting surfaces which are disposed at dierentl inclinations and are adapted to support difattached to the lowerportion of the standy ard and formed with coils and its side piecesstraddling the outer end of the standard and clamping spring, the sidepieces of said U-shaped spring'adapted to engage and hold a plateagainst the grinding wheel when 'placed on the outersupporting surface'and the lcentral portionA of the spring adapted to engage and hold aplate against the grinding wheel when placed on the inner grindingsurface. l

In testimony whereof I havehereunto set my hand in presence of twosubscribing Wit- HQSSSS.
